摘 要:土壤环境是人类生态环境重要组成部分。通过土壤A、B层元素含量特征参数对比、表层土壤环境地球化学分布特征、异常特征、环境容量状况评价,认为研究区内土壤环境状况良好,但土壤污染已从城区开始,向广大农村地区扩展,农作物所需的有机质及微量无素亏损严重,因此保护和改善土壤环境,已刻不容缓。Soil environment is a major constituent of human ecological environment. In the paper, by a contrast of the characteristic parameters of element contents in soil layers A and B and evaluation of the distribution characteristics of environment geochemistry, the anomaly characteristics and the environmental capacity conditions of soil, the authors conclude that the soil environment conditions are good as a whole. But soil pollution has already started from the urban areas and extended to the rural areas. The organic and trace elements which are needed by crops are seriously depleted. So, it is urgent to protect and improve the soil environment.
